The smart battery swapping cabinet can not only be applied to the fast charging and battery swapping of lithium batteries for electric two-wheelers/tricycles, but also respond to the wide range of small-capacity emergency charging needs in daily life, and provide users with more convenient power supply services and solutions. For low-speed electric vehicles, the battery swapping service is as convenient as portable charger. Users can quickly take out a fully charged lithium battery by scanning the QR code on the battery swapping cabinet to provide extra driving range for electric vehicles.
